High-pressure steel bottle sealing structure

ABSTRACT

An improvement of a high-pressure steel bottle sealing structure mainly consists of a cover body, a rubber ring and a bottle head whereby the cover body is designed with a convex point at the horizontal bottom which diameter is smaller than that of the inner diameter of the bottle head, and a rubber ring is found at the vertical side edge of the cover body with a thinner diameter than that of the horizontal bottom; the rubber ring is found at the vertical side edge of the cover body stopping at the air passage in order to resist inverse pressure and to prevent air leaking; the bottle head is found at the top of the high-pressure steel bottle and a ring base is designed in the middle of the passage such that the cover body inside stops at the ring base by using the convex point, and an additional length is also left at the bottle head for sealing procedure. Hence, the present invention provides a very rapid air sealing procedure of N 2 O, O 2  or other special gas.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an improvement of a high-pressure steelbottle sealing structure, especially one improving a high-pressure steelbottle sealing structure with a fast air-filling completed sealingprocedure.

2. Description of the Related Art

Commonly high-pressure steel bottle sealing structures mainly comprisesof a hat covering structure directly welded to the steel bottle and anoil-sealing cover matched with an oil leak-proof or an O-Ring sealingstructure stamped and filled into the steel bottle.

Therefore, much improvement is needed in the above-mentioned commonlyused high-pressure steel bottle sealing structures in order to obtain adisposable high-pressure steel bottle with a low capital cost and highmanufacturing quantity for more economical efficiency.

SUMMARY OF THE INVENTION

The present invention relates to an improvement of a high-pressure steelbottle sealing structure mainly consisting of a cover body, a rubberring and a bottle head whereby the cover body is designed with a convexpoint at the horizontal bottom which diameter is smaller than that ofthe inner diameter of the bottle head, and a rubber ring is found at thevertical side edge of the cover body with a thinner diameter than thatof the horizontal bottom.

The present invention relates to an improvement of a high-pressure steelbottle sealing structure mainly consisting of a cover body, a rubberring and a bottle head whereby the rubber ring is found at the verticalside edge of the cover body stopping at the air passage in order toresist inverse pressure and to prevent air leaking.

The present invention relates to an improvement of a high-pressure steelbottle sealing structure mainly consisting of a cover body, a rubberring and a bottle head whereby the bottle head is found at the top ofthe high-pressure steel bottle and a ring base is designed in the middleof the passage such that the cover body inside stops at the ring base byusing the convex point, and an additional length is also left at thebottle head for sealing procedure.

A BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 shows a combination of the high-pressure steel bottle sealingstructure.

FIG. 2 shows a plan of the present invention before sealing procedure.

FIG. 3 shows a plan of the present invention after sealing procedure.

FIG. 4 shows a plan of the high-pressure steel bottle.

DETAILED DESCRIPTION OF THE INVENTION

The present invention of a high-pressure steel bottle can be used infood processing such as butter processed into a foam for convenient usein butter foam coffee, or butter processed into a paste for use in cakedecorations. Hence, apart from requesting pureness of gas in the steelbottle, stable pressure is also important in order to attain a rapid andeffective purpose.

With reference to FIG. 1 showing a combination of the high-pressuresteel bottle sealing structure, the sealing structure of thehigh-pressure steel bottle 10 mainly consisting of a cover body 11, arubber ring 12 and a bottle head 13 is shown in the two diagrams indifferent angles. The horizontal bottom 14 of the cover body 11 isdesigned with a convex point 15 stopping at the ring base 16 found atthe middle of the passage of the bottle head 13.

With reference to FIG. 2 showing a plan of the present invention beforesealing procedure, high-pressure gas 17 goes through the cover body 11of the bottle head 13 containing rubber ring 12 into the air passagein-between to the steel bottle 10 which is than immediately sealed.

With reference to FIG. 3 showing a plan of the present invention aftersealing procedure, the top of the bottle head 13 is curved inwardly tothe top of the vertical side edge 18 of the cover body 11. The rubberring 12 is compressed in-between the horizontal bottom 14 and the top ofbottle head 13 and fills the air passage thus avoiding air-leaking andinverse flow of high-pressure gas 17.

With reference to FIG. 4 showing a plan of the high-pressure steelbottle, the high-pressure steel bottle 10 is a finished productcontaining high-pressure gas 17 and will not leak through bottle head 13or cover body 11 before use. Hence, the present invention provides avery rapid sealing procedure of N₂O, O₂ or other special gas.

1. An improvement structure of a high-pressure steel bottle sealingstructure mainly consisting of a cover body, a rubber ring and a bottlehead, wherein: said cover body is designed with a convex point at thehorizontal bottom which diameter is smaller than that of the innerdiameter of the bottle head, further, a rubber ring is found at thevertical side edge of the cover body with a thinner diameter than thatof the horizontal bottom; said rubber ring is found at the vertical sideedge of the cover body stopping at the air passage in order to resistinverse pressure and to prevent air leaking; said bottle head is foundat the top of the high-pressure steel bottle and a ring base is designedin the middle of the passage such that the cover body inside stops atthe ring base by using the convex point, and an additional length isalso left at the bottle head for sealing procedure, as characterized.
